3 Layout and Package Options

In system design, it would be nice to have flexibility of sharing different footprints on the same board. The THVD14x6 family come in two packages – SOIC (D) and SOT (DRL). An example of co-layout of these two packages is presented in Figure 10-2 in the data sheet of THVD14x6. For small footprints, VSSOP (DGK) is another popular choice instead SOIC. For example, THVD2450, THVD1550, and THVD1450 all have the VSSOP option besides SOIC. Similarly, two small packages VSSOP and SOT can be put on the same board with little layout effort as shown in Figure 3-1. This co-layout footprint can be considered for space limited boards.
